Proposals to rebuild Gabriel Davioud's Palais du Trocadero for the Exposition Internationale des Arts et Techniques dans la Vie Moderne (1937) in Paris resulted in Carlu's design for the Palais de Chaillot (with Louis Hippolyte Boileau and Leon Azema (1888-1978)), enclosing within its two curved wings parts of the original structure. The main feature, called the Fountain of Warsaw, is a long basin, designed by Roger-Henri Expert. The sculpture sits in one of the smaller cascading pools on the west side. On the east side is a complementary sculpture, 'Chevaux et Chien' (Horses and Dog) by Georges Lucien Guyot.
